Hashimoto Física, Astronomía y Matemáticas By spectroscopically analyzing the light emitted from the tip-sample gap of the scanning tunneling microscope(STM), we have investigated the carrier transport as well as the luminescence properties of AlGaAs/GaAsquantum wells (QWs). The emission intensity form a target well was measured as a function of the tip positionon a cleaved (110) surface of the QW structures. The thermalization length and the diffusion length of theinjected electrons were determined in real space. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434401 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.34 |
